Check Digit Verification of cas no

The CAS Registry Mumber 81009-03-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,0,0 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 81009-03:
(7*8)+(6*1)+(5*0)+(4*0)+(3*9)+(2*0)+(1*3)=92
92 % 10 = 2
So 81009-03-2 is a valid CAS Registry Number.
